OK! I know this was discussed before but will the 19.5 rims from these trucks (Frito Lay type truck) fit onto our D 350 axle's? I don't remember if a final answer was ever found. The reason I'm asking is I am putting a 93 dually axle into my truck and if these wheels will fit this is the route I would like to go.I do remember some talk that the center hole was to small. If that is the case could it be bored out to make it fit? Has any one else put these rims on your truck and what did you do to make them fit. Sorry to bring this up again but I'm trying to get things lined up for the axle install.

You will have to open the center hole up. I have a set in the garage that I no longer run. These are very, very heavy tires and wheels. You will feel a big difference.

That looks pretty darn Heavy Duty to me.

There is a 1st Gen. Dodge that I see several times a week that is running all six wheels/tires from a step-van.

The guys neighbor has a machine-shop and they just lathe-cut the centers to be an exact match to the original Dodge wheels.

One thing to be sure and get are those flat plates that go on top of the wheels, and then the Dodge conical nuts fit in them just like the GM ones did.


If you don't get those flat plates (it is a GMC/CHEVY thing, nobody else ever used them), another option is to replace the studs with 1983-86 Ford DRW studs/nuts, as the Ford nuts have integral flange-washers; the flange-washers are loose on the nuts, such that the nut can keep turning once the washer contacts the wheel; a much better set-up than those one-piece jokes that Dodge has.

Thanks Dig'umz,That is a nice looking set up you have. When you say heavy is it because they are commercial tires? Does the truck ride rougher? Did you bore the center hole to make them fit? Can you feel a difference in acceleration,handling and a loss of fuel mileage? The reason I would like to try this set up is for towing my camper. I'm looking for more stability. Bear killer I will look at a Frito truck next time I see one. I can just about picture in my mind what you are talking about. I have a set of the Dodge lug nuts you are talking about and the nut has a chamfer of somewhat on the rim side of the nut. Has there been a problem with this nut seating properly?

The solid flanged one-piece Dodge DRW nuts have two faults; one fault being that the flange, being a solid part of the nut, must still turn after it contacts the wheel-face; the other fault is that the coined wheels are lug-centric and the flanged nuts will not center the wheel to the hub.

Dodge soon realized their mistake with the wheel-centering and advised to center the wheels with plain old conical nuts, then once the wheels are centered, remove the conical nuts and install the flanged ones.

My take on that scenario is to simply replace ALL of the flanged nuts with plain old conicals and be done with it.



As to the GM plate I mentioned, look at any GM DRW truck and it will have these plates between the lug-nuts and the wheel-face.

The wheel-faces are flat and the lug-holes of the plates are coined for conical nuts.

When you actually see one, what I am trying to explain will be obvious.

Yes, I had to bore the centers. I would bet that one 19.5 tire and wheel weigh more than two 16's. You will feel it in the steering, braking, and acceleration. My truck was already rough riding, so its not a huge difference. I loved the look and may go back to them some day when my front end is tighter and the rear is bagged. As far as stability goes you should be fine.

BearKiller

dig'umz, when you had the 19.5s on your truck, did you use the GM plates that I mention, or did you approach it from a different angle ??




The guy that owns the truck that I mentioned having the 19.5s does a lot of heavy towing and claims that he simply loves them; he says that, when he sets into a curve, they handle much more like a bias tire, without the typical spongy radial lurching and just stand up there and take the curve.


He has convinced me to keep my eye out for a set and put them on my truck; my only hesitation is that there are seven trucks and several trailers and EVERY TIRE we have is a 235-85-16, which makes life a lot easier and much less expensive.

On the back I cut it to match the stocker and used the stock lug nuts. For the front I used a bigger drill bit to bevel two of the lug nut holes. That way it could be centered with acorns and use the stock nuts. I don't tow anything, this truck has never had a gooseneck in it. If I did, I may have liked these tires more. I sure liked the way they looked.

AUGIE DOG

I forgot to ask what size tires were mounted on the rims?

dig'umz

225 70 19.5

BearKiller

If my memory serves, the 225-70-19.5 is almost exactly the same height as a 235-85-16, within a tenth of an inch or so.


If it isn't, then it is another 19.5 size, as I found one in my research that is almost an identical match.

justinsdad

a 225-70-19.5 is 31.90 tall and 8.6 wide,

the 235-85-16 is 31.73 tall and 9.25 wide, so there pretty close.

dig'umz

Yes you are correct, other than weight they are almost identical.
